Weird clicking sound as I accelerate out of corners.

Experiencing an odd effect here. My car is running fine, but when I accelerate out of corners, there's a metallic clicking noise that is very loud. It only clicks while I have my foot on the gas; when I let off it goes away and doesn't come back. It sounds like something may be making contact with the driveshaft or wheels, but I'm not seeing any clearance issues at all under here. Driving down the road it's nonexistent.

As o said, it sounds metallic, like contact, though sometimes I swear it sounds like something is sparking. That said, it doesn't dim the lights or cause any charging issues at all.

Any ideas where to look? I'm stumped.

EDIt: I should add, the clicking cannot be replicated in neutral or park, has to be in drive. The noise appears to be coming from the center-right side, probably further back than the engine bay. Honestly sounds like the exhaust pipe is hitting something, but under the car I can't see where.

EDIT EDIT: the car has new axle bearings and brand new front wheel bearings. The driveshaft is tight, not much play at all in the u joints. Transmission is full of clean fluid. The noise only started after replacing my muffler and removing the tailpipe.
